  C. To serve as a blueprint for development
  D. To understand how the flow of value can be improved
  E. To add or remove user segments based on business decisions
  B. To gain insight into organizational efficiency
  D. To understand how the flow of value can be improved

  ---

  Explanation

  Mapping the value stream helps accomplish two actions: to gain insight into organizational efficiency and to understand how the flow of value can be improved. A value stream is the series of steps that an organization uses to implement solutions that provide a continuous flow of value to a customer. Mapping the value stream involves identifying the steps, people, inputs, outputs, tools, and metrics involved in delivering value from concept to cash. By mapping the value stream, the organization can gain insight into the current state of the delivery process, such as the lead time, cycle time, throughput, quality, and waste. This insight can help the organization identify bottlenecks, dependencies, handoffs, delays, and inefficiencies that affect the flow of value. Mapping the value stream also helps the organization understand how the flow of value can be improved by applying the principles and practices of DevOps, such as culture, automation, lean flow, measurement, and recovery. By improving the flow of value, the organization can increase customer satisfaction, reduce costs, accelerate time-to-market, and enhance business agility

  Explanation

  The Continuous Delivery Pipeline (CDP) is a key element of the Agile Product Delivery competency in SAFe. It represents the workflows, activities, and automation needed to guide new functionality from ideation to an on-demand release of value. The CDP consists of four aspects: Continuous Exploration (CE), Continuous Integration (CI), Continuous Deployment (CD), and Release on Demand. CE focuses on creating alignment on what needs to be built, using design thinking and hypothesis-driven development. CI focuses on building quality into the solution, using practices such as test automation, code analysis, and continuous feedback

• Question 74:

  What is one benefit of DevOps?

  A. Better alignment between strategy and execution
  B. Increased batch size
  C. Tightly coupled architecture
  D. Fewer defects
  A. Better alignment between strategy and execution

  ---

  Explanation

  According to the SAFe DevOps Practitioner 6.0 study guide1, one of the benefits of DevOps is better alignment between strategy and execution. DevOps is a mindset, culture, and set of technical practices that supports the integration, automation, and collaboration needed to effectively develop and operate a solution. DevOps helps break down organizational silos and develop a Continuous Delivery Pipeline (CDP) -- a high- performance innovation engine capable of delivering market-leading solutions at the speed of business. By aligning strategy and execution, DevOps enables teams to deliver value to customers faster and more reliably, as well as to adapt to changing market conditions and customer needs. Therefore, better alignment between strategy and execution is one of the benefits of DevOps.

• Question 75:

  What falls outside the scope of the Stabilize activity?

  A. Continuous security monitoring is done
  B. Features are monitored after release
  C. Blue/green deployment
  D. Failover and recovery processes are in place
  C. Blue/green deployment

  ---

  Explanation

  Blue/green deployment falls outside the scope of the Stabilize activity. The Stabilize activity is part of the Release on Demand aspect of the Continuous Delivery Pipeline, which is responsible for releasing new functionality to end users, either immediately or incrementally, based on business and customer needs. The Stabilize activity ensures that the solution is working well from a functional and nonfunctional perspective, and that it can be operated and supported effectively. The Stabilize activity involves the following practices: Continuous security monitoring ?Applying automated tools and processes to detect and respond to security threats and vulnerabilities in the production environment, and ensuring compliance with security policies and standards. Failover and recovery processes ?Establishing and testing backup and restore mechanisms, disaster recovery plans, and business continuity procedures, to ensure the availability and resilience of the solution in case of failures or disruptions. Features monitoring ?Collecting and analyzing data on the usage, performance, and outcomes of the released features, to measure their value and impact, and to identify any issues or defects that need to be fixed or improved. Support and maintenance ?Providing ongoing support and maintenance for the solution, such as resolving incidents, handling requests, applying patches, and performing upgrades, to ensure the reliability and quality of the solution. Blue/green deployment, on the other hand, is a technical practice that belongs to the Continuous Deployment aspect of the Continuous Delivery Pipeline, which is responsible for deploying new functionality into the production environment, where it can be tested and validated. Blue/green deployment is a change management strategy that reduces the downtime and risk of deploying new versions of software. It involves having two identical but separate environments: one is the active environment that serves the user traffic (blue), and the other is the inactive environment that hosts the new version of the software (green). The deployment process consists of switching a small portion of the user traffic from the blue environment to the green environment, after verifying that the new version is working properly. The portion of users who receive the new version are called canaries, as they serve as early indicators of the quality and performance of the new version. If the canary release is successful, the entire user traffic is gradually switched to the green environment, which becomes the new active environment. If the canary release fails, the user traffic is switched back to the blue environment, which remains the active environment. Blue/green deployment has several benefits, such as: It allows for fast and reliable rollback, in case of any issues or errors in the new version, by simply switching back to the active environment. It eliminates the need for complex and error-prone migration scripts, as the inactive environment can be prepared and tested in advance, without affecting the active environment. It enables testing and experimentation of the new version with a subset of users, by directing some user traffic to the inactive environment, before switching completely. It facilitates continuous delivery and deployment, by automating the switching process and reducing the transaction cost and risk of moving changes to production

• Question 76:

  What does the %CandA metric measure in the Continuous Delivery Pipeline?

  A. The percent concurrent and accurate process times of each pipeline activity
  B. The percent complete and average times of each pipeline activity
  C. The percent of change averages of each pipeline activity
  D. The percent of time downstream customers receive work that is usable as-is
  D. The percent of time downstream customers receive work that is usable as-is

  ---

  Explanation

  The %CandA metric measures the percent of time downstream customers receive work that is usable as-is in the Continuous Delivery Pipeline. The %CandA metric is a measure of the quality of the work output from a process step. It indicates the percentage of time that the downstream customers receive work that is acceptable as is, without any rework or errors. To calculate the %CandA metric, the people responsible for the next step need to inspect the work output from the previous step and determine whether it meets the quality standards and expectations. They also need to provide feedback to the previous step on the defects or issues they find and how they affect the value stream. By measuring the %CandA metric, the enterprise can gain insight into the current state of the delivery process, such as the lead time, cycle time, throughput, quality, and waste. This insight can help the enterprise identify bottlenecks, dependencies, handoffs, delays, and inefficiencies that affect the flow of value. The %CandA metric can also help the enterprise understand how the flow of value can be improved by applying the principles and practices of DevOps, such as culture, automation, lean flow, measurement, and recovery. By improving the %CandA metric, the enterprise can increase customer satisfaction, reduce costs, accelerate time-to-market, and enhance business agility

• Question 77:

  What is a core DevOps principle?

  A. Lean Budgets
  B. Culture
  C. Servant leadership
  D. Iteration review
  B. Culture

  ---

  Explanation

  Culture is a core DevOps principle. DevOps is not only a set of technical practices, but also a mindset and a culture that supports the integration, automation, and collaboration needed to effectively develop and operate a solution. DevOps culture is based on the following values and behaviors: Shared responsibility ?DevOps culture fosters a sense of shared ownership and accountability for the entire solution lifecycle, from ideation to operation. Development and operations teams work together, not only to help each other, but also to ensure that the overall organization succeeds. DevOps culture eliminates the blame game and the silo mentality, and encourages mutual trust and respect among all stakeholders. Continuous learning ?DevOps culture promotes a culture of continuous learning and improvement, where teams are constantly seeking feedback, experimenting with new ideas, and learning from failures. DevOps culture embraces a growth mindset, where teams are not afraid to try new things, challenge the status quo, and learn from their mistakes. DevOps culture also supports a learning organization, where teams share their knowledge and best practices, and leverage the collective intelligence of the whole enterprise. Customer focus ?DevOps culture emphasizes the importance of delivering value to the customer, and aligning the solution to the customer needs and expectations. DevOps culture applies customer-centric and design thinking approaches, such as personas, empathy maps, and customer journeys, to understand and empathize with the customer problems and desires. DevOps culture also validates the assumptions and hypotheses about the customer value proposition, by collecting and analyzing data and feedback from the customer. Automation ?DevOps culture leverages automation to improve the efficiency, quality, and reliability of the solution delivery process. DevOps culture applies automation to various aspects of the Continuous Delivery Pipeline, such as testing, integration, deployment, monitoring, and security. DevOps culture also uses automation to reduce manual work, eliminate human errors, and accelerate feedback loops5
